Application filed April 15, 1914. Serial No. 832,087.

To all whom t may concern.' i

Be it known'that we, RAPHOEL Cook and OTTO LINDLEY, citizens of the United States, residing at Cosby, in the county of Andrew and State of Missouri, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

Our invention relates to improvements in lift and force pumps, and particularly to that type in which a piston is reciprocab e within an. open top cylinder, during a pumping operation, to forcibly discharge the water acted upon through a suitable stand pipe which, in the present instance, also acts or serves as the piston rod.

rlhe invention consists in the construction and arrangement of parts as will be hereinafter fully described and claimed. In the said description, reference will be had to the accompanying like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the pump, the well or receptacle from which the liquid is forced being shown in section; Fig. 2 is a similar view, the piston having been forced to the end of its downward stroke; Fig. 3 is a top plan view of the pump; Fig. 4 is an enlarged longitudinal sectional view of the cylinder and piston;'and Fig. 5 is a detail perspective view illustrating the manner in which the platform or pedal is supported. p

Referring now to the drawings by numerals, 1 designates the ,well or receptacle from which the water or other liquid acted upon is drawn. Suspended within the said well and a suitable distance beneath or below the normal water line thereof, is an open top cylinder 2 within which a piston designated as an entirety by the numeral 3 operates. Any suitable means such as the hanger bars f1 may be provided to suspend the .cylinder in the manner above set forth, the said bars, as shown, being attached to the well top designated. Threaded, as indicated at 6 to the piston 3 is a stand or discharge pipe 7, said pipe extending upwardly through the well top 5 and terminating in a suitable spout 8 terminating at a point directly over and above a suitable trough 9.

PivotallyA connected as at 10 to the free end of the lift pipe 7 is a link drawings wherein l or connection Patented Mar. ae, ieia.

11, the opposite end of vwhich is in turn pivoted as at 12 to an operating lever 13 Vfulcrumed intermediate its ends 'at a point 14, a suitable stand 15 acting as a support for the lever at its fulcrumed point. The opf posite end of the lever 13 from that pivoted to the link 11 has secured thereto as indicated at 16 helical springs 17, the opposite ends of which are attached in any suitable manner tothe ground.

y Ports 18 are formed within the pistonr, preferably at diametrically opposite points, which ports, during the downward stroke ofthe piston, are automatically closed by flap valves 19 pivoted as at 20 to the under -side of the piston. Upon the upward stroke of the piston 3v valves 19 automatically open while the valve 21 pivoted as at 22 within the pipe stand 7, automatically closes, this operation, as is obvious, providing for a refilling of that portion of theefcylinder below the piston 3. y' l As a means whereby the lever 13 may'be oscillated, a platform 23 has been provided, said platform being hingedly connected as at 24; to the base of the support 15, its free end being pivoted as at 25l t`o a suitable frame 26 vin turn connected as at 27 to the lever 13 at a point adjacent the pivot point 12.

Operation When it is upon he pumped, pressure bear upon platform or pedal 23, causing lever 13 to be oscillated and stand pipe 7 to be forced downwardly. The said pipe 7 being rigid with piston 3, the latter executes of the pump is as follows'. desired that the iquid acted isV brought to its downward stroke, forcing water within the cylinder and below the piston to open valve 21 and llow through the said pipe 7 and spout 8 into the trough or receptacle 9. By relieving the'platform or -pedal Q3 of the pressure, springs 17 will return lever to its normal position indicated in Fig. 1, allow pipe 7 to move upwardly and piston 3 to execute its upward stroke, in which event valve 21 will automatically` close and the valves 19 automatically open to permit a refilling of that portion of the cylinderbelow the piston 3.

A suitable bearing such as is indicated at 28 may be arranged within the cylinder to maintain the pipe stand concentrically therein. r

From the foregoing, taken in connection lll) with the accompanying drawings it is appar. A

,ent that operation is effected by pressure upon platform 23;-that'the operation of the several valves is positive and automatic; and

fthat by the provision ofv they springs 17, piston 3 is forced to' execute its .upward stroke to provide for continuedoperation cf the pump. Attention is ,also called to the fact that springs 17 may be disconnected, and operating leverlS actuated byhand and irrespective of pressure upon platform 23.

In reduction to practice, -We have found that 4the Aform of our invention, illustra-ted- `ficing any of the advantages of our invention, as defined in the appended claim..

Having thus fully described our invention, what we claim as new and desire to In combination with a force pump; actuating means therefor including an upright comprising spaced standards, an elbow mounted` on each standard, the respective elbows being arranged to open inwardly, and a connecting bar fitting the respective elbows,"the latter servin asbearings therefor, said -ba'r being osci latable; an operating lever having connection withv the bar,

Asaid bar acting las a fulcrum for the lever;

lateral extensions formed on one end of the lever; a spring having connection with the extension terminals to normally maintain one end of said 1ever.elevated;-a treadle -hingedlylconnected to the upright at its base; .a connection between the lever and the free end of said treadle to normally maintain the latter in an elevated position; and a connection between the lever and the pump mechanism` to actuate the latter through/movement of Said treadle against tension of the spring aforesaid.

In testimony whereof we alix our signatures in presence of two witnesses.
